John Deere really beefed up the rear end in the 4230 it had a 3pt rating of 4700# verses 3700# on the 4020.It also had the ability to have 3 remote circuits. The engine oil cooler is much different. Engine oil capacity went to 17 quarts and a spin on oil filter was added.The tractor sits much higher being about the size of a 4520.The wide front end went to a cast iron design.

Get real-have you ever seen a 4520? They're bigger than a 4630.

I was surprized too when a local dealer had a 4520 next to a 4230. Neither had cabs. The hood and seating position was very very close to being identical.Same with length. I not trying to say a 4230 could compete with a 4520 out in the field. I'm trying to point out how much bigger in physical size a 4230 is over a 4020.

Thanks for the information. One thing I would like to know is how all you guys know this detail about the different models of JD? Is this in the manuals or is it through experience?

IT depends on how you want to look at it but this is my read on what jd did. usually deere would replace a certain model with one of a little more power,but in this case they depowered the 4020 in 1973 and called it a 4030 which has 80 pto hp.(the 4020 is 95 pto hp.)then they brought in the 4230 to narrow the gap between the 4030 and the 4430.during the 20 series,deere did not produce an 80 hp tractor.

the 4230 is a 100 hp tractor.it has the same engine as the 4020 but they came out with the quad.range trans,also they changed to a hyd clutch instead of manual,and on the syncro and quad.range transmission they used a wet clutch. and the entire tractor is a little larger than the 4020 by about 1500lbs.

I'm afraid this has caused confusion since the 30 series was introduced. The 4030 is not a de-powered 4020. The 4030 has a 329 6-cylinder engine. At the time Deere had quite a h.p. gap between the 3020 (71 h.p.) and 4020 (96 h.p.-late ones) that IH and others were happy to fill. Most of the competition was 6 cylinder as well, with the 3020 being 4 cylinder. The 4030 was introduced to fill that h.p. gap and be a 6 cylinder tractor, too. The 4230 is a replacement for the 4020, with both having a 404 cubic inch engine, although the 4230 is a completely different style of engine. Sorry to be a stick-in-the-mud. Hope this helps. Mike

Mike, your info is 100% correct here, except for the fact that the 4030 WAS aggressively promoted, at least in the Northeast, as the replacement for the 4020 by sales staff. Unfortunately for those that bit on the concept, while being a nice little tractor in its own right, the 4030 was no match for even a medoicre 4020, without the addition of an M&W turbo and 38" rubber. The reputation of the 4030 was doomed from the start because JD could't successfully promote the 4230 as the new 4020 because of the drastic price difference, and chose instead to pass off the 4030 as an adequate replacement, which it usually wasn't.

Thanks for all the information, which is most helpful and interesting. I'm not nearly as knowledgeable as all of you on this issue.

My seat in my 4230 is quite worn and I would like to replace it, but would like a higher back. What you all of you suggest for a replacement seat?

Also, would a front end loader (JD type, presumably stock) from a 4020 fit on a 4230?
Thanks again.

From the 4020-4230 era, a 48,58,148, or 158 loader with 'row crop' tractor mounts will make a good match for a 4230. Lean towards the 148/158 due to dual bucket cylinders and greater lift specs, while sacrificing on/off ease. If currently on anything from a 2510 to 4320, it will fit right on the 4230.
